CVE-2024-49937

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: Set correct chandef when starting CAC When starting CAC in a mode other than AP mode, it return a "WARNING: CPU: 0 PID: 63 at cfg80211_chandef_dfs_usable+0x20/0xaf [cfg80211]" caused by the chandef.chan being null at the end of CAC. Solution: Ensure the channel definition is set for the different modes when starting CAC to avoid getting a NULL 'chan' at the end of CAC.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: wifi: cfg80211: Establecer chandef correcto al iniciar CAC Al iniciar CAC en un modo distinto del modo AP, devuelve un "ADVERTENCIA: CPU: 0 PID: 63 en cfg80211_chandef_dfs_usable+0x20/0xaf [cfg80211]" causado por chandef.chan que es nulo al final de CAC. Solución: Asegúrese de que la definición del canal esté configurada para los diferentes modos al iniciar CAC para evitar obtener un 'chan' NULL al final de CAC. Seguimiento de llamadas: ? show_regs.part.0+0x14/0x16 ? __warn+0x67/0xc0 ? cfg80211_chandef_dfs_usable+0x20/0xaf [cfg80211] ? report_bug+0xa7/0x130 ? exc_overflow+0x30/0x30 ? handle_bug+0x27/0x50 ? exc_invalid_op+0x18/0x60 ? handle_exception+0xf6/0xf6 ? exc_overflow+0x30/0x30 ? cfg80211_chandef_dfs_usable+0x20/0xaf [cfg80211] ? exc_overflow+0x30/0x30 ? cfg80211_chandef_dfs_usable+0x20/0xaf [cfg80211] ? regulatory_propagate_dfs_state.cold+0x1b/0x4c [cfg80211] ? cfg80211_propagate_cac_done_wk+0x1a/0x30 [cfg80211] ? process_one_work+0x165/0x280 ? worker_thread+0x120/0x3f0 ? kthread+0xc2/0xf0 ? process_one_work+0x280/0x280 ? kthread_complete_and_exit+0x20/0x20 ? ret_from_fork+0x19/0x24 [acortar asunto, eliminar OCB, reordenar casos para que coincidan con la lista anterior]
